Answer:
A Carbon Dioxide ( CO2)
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
Answer:
so what’s the question?
Answer:
This is in order to maintain the species number of chromosomes.
Explanation:
Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.
Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .
During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.
Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.
